Dematerialization
Dematerialization is the reduction of material throughput required to provide a product, service, function, or level of economic activity. Applying Dematerialization requires a stated material pathway, lifecycle stage, retained function, waste status, and end-of-life route. Those choices determine how Dematerialization can be compared or acted upon.
In simple terms
In practical use, Dematerialization is the reduction of material throughput required to provide a product, service, function, or level of economic activity. For Dematerialization, the label organizes a condition or relationship but does not by itself demonstrate performance or compliance within a declared material pathway, lifecycle stage, retained function, waste status, and end-of-life route. Dematerialization connects with Waste prevention and Waste hierarchy; each can affect its application without sharing its definition. The candidate link between Dematerialization and Urban symbiosis remains a separate expansion question supported here by International Resource Panel.
Why it matters
Dematerialization matters because decisions about it determine which lifecycle route is preferred, how much function or material value is retained, and where responsibility ends. A defensible use of Dematerialization therefore exposes its boundary, method, evidence, responsible actor, and uncertainty before a conclusion is accepted. That discipline keeps Waste prevention and Waste hierarchy from being treated as proof of Dematerialization when their criteria, scope, or results differ.
Example
A product and materials team evaluates Dematerialization for a defined decision and records the relevant material pathway, lifecycle stage, retained function, waste status, and end-of-life route. For Dematerialization, the team uses cited material from International Resource Panel to frame the decision and distinguish the idea from adjacent concepts, documenting the period, data, assumptions, and comparison with Waste prevention. It treats Waste hierarchy and Urban symbiosis as separate questions rather than proxies for Dematerialization.
How it differs
Waste prevention
Dematerialization is a concept; Waste prevention has a different function. Evidence for Waste prevention does not establish Dematerialization unless both sets of applicable criteria are met.
